In my previous article where I found the average of a list in Python without using imports, in this article I want to expand how you could apply the same concept, but to two-dimensional lists. Thankfully, if you know how to find the average of a one dimensional list in Python, you can simply expand …
How do you sort a two-dimensional array in Python easily without importing libraries? Thankfully, some native functions in Python make sorting arrays a breeze. I recently had a project where I had the following data structures, representing each unpaid invoice by the customer, the days they were overdue and how much was outstanding. Here’s a …
How do you calculate the simple average of a list of numbers in Python, without needing to import any libraries? Unfortunately, there’s no native average or avg function in Python to easily calculate the average of a list containing just numbers: To calculate the average of a list of numbers in Python, use the sum …
